I have a question about AB's whereabouts on those days. Has anyone said that he has an alibi? Isn't it possible that he was using her phone or at the very least, in the car? When my dh and I are out and about, he drives and I have my phone. His family calls on my phone and he makes calls from it. He has his own, but when we're out, we just use mine. So, if we were investigated, all pings would come from my phone, even though we're always together and I may not be the one using it.
